Abstract

The glands in the human esophageal mucosa have been considered rudimentary, and have been poorly studied. Only recently, their role in the defense of the esophageal mucosa in gastroesophageal reflux disease has been put in evidence. In the present study, the presence of the different esophageal gland types was observed in 82 necropsy specimens. A precise topographical study was possible in 15 specimens. Cell proliferation parameters, namely DNA synthesis and mitotic index values in the squamous epithelium and in the esophageal glands were measured in 8 patients undergoing a surgical palliative esophagectomy, after in vivo labelling with bromodeoxyuridine. Upper mucosal, lower mucosal, and submucosal glands were observed in respectively 3.7%, 87% and 99% of the 82 esophageal specimens. Our topographical analysis showed that the upper mucosal glands, lower mucosal glands, and submucosal glands are occupying respectively 0.02%, 2.61%, and 3.96% of the esophageal surface. DNA synthesis and mitotic index values in the progenitor zone of the squamous epithelium were respectively 7.91% and 0.81%, whereas the proliferative activity in the glands was extremely low. The labelling index In the excretory ducts of the glands was only 0.07%,...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
